# Exploit Title: Online Marriage Registration System (OMRS) 1.0 - Remote code execution (3)
# Date: 10/02/2021
# Exploit Author: Ricardo Ruiz (@ricardojoserf)
# Vendor Homepage: https://phpgurukul.com/
# Software Link: https://phpgurukul.com/online-marriage-registration-system-using-php-and-mysql/
# Version: 1.0
# Tested on: Windows 10/Xampp Server and Wamp Server
# Porting an existing exploit (https://www.exploit-db.com/exploits/49260, for macOs) to Linux/Windows. Adding the possibility of automatic registration and execution of any command without needing to upload any local file
# Example with registration:    python3 script.py -u http://172.16.1.102:80/ -c 'whoami' 
# Example without registration: python3 script.py -u http://172.16.1.102:80/ -c 'whoami' -m 680123456 -p dante123
